Application filed February 25, 192-2. Serial No. 539,271.

To all whom it may concern:

Be it known that 1, CHARLES D. MELTON, a citizenof the United States, and a resident of Eustace, in the county of Henderson and State of Texas, have invented certain new and useful Improvements in Presses, of which the following is a specification The present invention relates in general to presses, and: more particularly to a hay press or baler..

Theobject of the invention is to provide an apparatus of this character which is adapted to automatically and efficiently feed the material into the baling chamber in-a manner to permit of continuous operation, which rapidly forms the bale and in which the feeding and baling operations are ac curately timed and occur in rapid and-continuous sequence. v

Another object is to provide a hay press or baler embodying a plurality of swinging hoppers or bale boxsections adapted to be successively loaded and swung into and out of alignment'with the press box.

Another object is to provide an apparatus of this character which may be operated by horse power, or from a gasoline'engine or any other suitable type of power'pla'nt, and which is of simple and durable construction, reliable in operation and easy and inexpensive to manufacture. 7'

Other objects and advantages of the in' vention'reside in certain novel featuresof construction, combination and arrangement of partswhich will be hereinafter more fully described and particularly pointed out in the appendedclaims, reference being had to the accompanying drawings. forming part of this specification, and in which:

Bars or standards 15 and 16 are carried by the body portion, the "members of the pairs being. disposed upon the opposite sides of the body portion, and the pairs themselves being spaced longitudinally on the body portion from each other. Transversely extending sills 17 and 18 are secured to the underside of the body portion and project beyond the sides thereof, the sills being con nected with cross beams 19 and 20;arranged above the sills by means of uprights 21' and 22. Boththe sills l7 and 18'and the cross beams '19 and 20 are connected with the standards 15 and 16.:"Adjace'nt the upper end of the standardscross pieces 23 and 24 a refa'rranged and are connected thereto to complete the framework of the bail or press end of, the apparatus. V

A- baling or compressing chamber 30 is provided, beingrmade up of longitudinal ,cluded in the tension device.

pieces 31, 32 and 33 superposed on each other in edge'jt'o edge relation and suitably secured to the framework. These pieces extend rearwardly of the framework and coact with the tension device 35 at the delivery end of thecompression chamber, uprights 36 being in- The body portion or reach is provided on its underside with a plurality of cross bars 37.

A plurality, preferablya pair, of pivoted hoppers or bale box sections; designated at 40 and 41,- isprovided and is adapted to be successively brought intopos'ition over the baling chamber in complementary relation thereto. The hoppers 40 and 41 are pivotally connected to the opposite" sides'of the bale chamber 30, the section 40 being. secured to one side by means of a hinge 42, and the bale section 41 being connectedat the opposite side by means of a hinge 43. When one of the hoppers is superposed on the baling. chamber to; feed its material thereto and to otherwise complement the same, the other" hopper is swung outwardly away from the baling, chamber, with its center line substantially at rightangles to the center line of the bal-ing chamber. Platforms 46 and 47 are mounted upon thec'r'oss beams 19 and 20. and uprights 21- and 22 and serve to receive the hoppers 40 and- 41 respectively when the hoppers are swung outwardly away from the baling chamber. Feed chutes 48 and 49 are associated with the platforms 4 6 and 4'7.

Locking mechanisms are provided for releasably securing. the bale sections in positionwhen superposed on the baling chamber in complementary relation with respect thereto. Two such locking mechanisms are carried by each section and as'they are identical in construction, a common description will serve for all. Each; includes a latch 50 pivoted to the end walls of the hopper and connected by means of a short link 51 to one end of the bell crank lever 52,. the other arm of which is connected to the retractile coil spring53 which is effective to urge the latches to locking position whereby when the hopper is superposed'on the baling; chamber the hooked end of each latch snaps over an adjacent pin 54 and 54 provided on the framework and constituting a keeper for the latches.

A toggle is associated with each of the hoppers and each serves as a means for, swinging the hopper from loading. position that is from its position-0n the loading platform with its center line substantially at rightangles to the centerline of the bali-ng chamberto the position in which it i-ssuperposed on the b-al-ingchamb'er that is to baling position. Each toggle comprises an upper inverted U-shaped link 55 having drums 56' provided with trunnions 57' 1 0-- tatabl journaled in bearings 58 fixed to the side wall of the hopper and having its body portion 59 pivotally connected with the ends of the arms 61 of the lower U- .shaped link 62, the body portion 63 of which A crank 65 1s cooperatively arranged with 1 respect to" each toggle and each includes bearing portions 66 rotatably mounted in bearings provided therefor on the framework, crank arms 67 and a wiper bar 68 extending transversely of the crank arms 1 and adapted tohave wiping engagement with the arms61 with-'the'lowerlink of the adjacent toggle for swinging the sections controlled by the toggle from loading position to: a position complementary to the i bale-chamber.

.A- pair of upwardly. extending. arms 70 ispca rried by each crank, the arms being oflset from the crank arms by means of extensions 71 ,formedon the wiper bar and the free ends of the arms having lateral lugs-72. Links 73 are pivotally connected at their ends to the arms 7 0 and constrain these arms and the crank'65 to which they are connected to corresponding. motion;

Flexible elements, such aschains or the like,, designatad at 75,"are connected'at one end with the lugs 72 and areconnected at their opposite ends tov the bell crank levers 52, the connection to these levers being such that a pull exerted .by the flexible element opposes the tensionof the 'retractile coil spring and disengages the latch. from its keeper. This disengagment' of the latch is the initial action incident to a pull being exerted uponthe flexible element asafter this initial releasing actionthe pull is effective to swing the hopper from b-aling position outwardly to loading position. It is obvious therefore that when the cranks .67 are swung outwardly they exert a pull upon the flexible element by means of the arms 70- to effect this action and when the cranks are swung inwardly the wiper bars 68 have wiping engagement with the arms 61 of. the

lowerlink 62'of the togglefto swing the hopper upwardly from loading-to baling.

position. As the cranks 65 are constrained to corresponding. motion, one of the cranks is exerting a pull by means of the arm 70 upon its flexible element when'the other is coacting; with-"the toggle whereby one hopperisshifted from-balingzposition-into loading position and the other section is shifted from loadingpositioninto' baling position. It s to be noted that the hopper in baling position is first shifted into loading position and immediately .thereafter the .hopper in loading position is shifted. into baling position, the flexible elements 75' andarms acting before the cranks65 t0 effect this sequence. r

' A trampendesignated generally at 80 is mounted upon the framework and includes a head-81 carried at the lower end of a rod 82 slidably mounted in a bearingprovided therefor in guide bars 84 and 85. A cross head 86 is arranged at the upper end of the rod 82, and guide rods 8'7 are connected at one end to said cross head and at the other end to the tramper head and operate in guide openings 88 and 89 providedtherefor in. the guide bars 84 and 85.

.A' walking beam 90 is provided and has rollers 91 operating'in a channel iron 92 constituting a guideway and has its yoke end connected by means of connecting rods 93 with the tra-inper head and the other end pivotally supported on carrier IOClS 9h by means of. the pivotal connections 95, the

' rods 94 being bifurcated at their'op'posite ends and the bifurcated ends being pivotally connected to cross bolts 96 carried by the uprights 36. w

A shaft 98 is rotatably mounted in bearings 99..carried upon the uprights'2l and 2:2 and has a crank arm 99 at one end pivotally connected to one end of an angled connecting rod 100, the opposite end of-which is pivotally connected to the walking'beam 90. Crank arms 99 coact with the stop element 101 which extends laterally from a bumper plate 102 carried by the top of the compression chamber and serving to receive the impacts incident to the movement of the walking beam. WVhen the'crank arm 99 engages the stop element 101 it has moved to such position that the weight of the trampe'r and the walking beam is effective to exert an outward thrust upon the crank arm to lock the crank arm,v walking beamand tramper head in elevated position.

Spring pressed or pivoted stops or checks, 102 are associated with the baling chamber and each includes a pivoted body portion 103 operating between the longitudinal body piece and actuated by springs 10t.- 1

it plunger, designated generally'at 105 is operatively mounted in the compression chamber.

.108 interconnected with each other and braced by means of vertical straps 109 and transverse strap 110. A plunger rod 112 is pivotally connected to the plunger by;

ing a flat bearing surface 1171,,A1metallib apron "118 has a stationary section 1191;

The plunger (see'Fig. 10.) in-' cludes a plunger head comprising a head. plate 106, av base plate 107 and a top platerigidly secured to the top plate of the plunger and .has I a swinging. section 1120 hingedly connected, as at'121, tothe stationary section and limited in its downwardly swinging movement by engagement with the flatbearing surface of the stirrup 116. The plunger. rod extends longitudinally of the frame or body portion to'the power end of the press..;, J

.'At the power end of the press a bed plate 125 is fixed to the reach or body portion 10 and a power block 130 is rotatably mounted upon a postv 131 upstanding from the bed plate 125', the base of the block resting upon acircular bearing plate 132 to slightly space the power block from the bed plate. A drivendisk 133 is fixed to the upper end of the power block and may be driven by horse power by meansv of sweeps 134- or may be driven from amotor bymeans of suitable gearing. 135 main driving arm 136 which includes a metallic casing 137 having a roller l37 'jour naled in the outer end thereof, and ata diametrically opposite point the; power block isv provided with a second driving arm 138. The casing 137 .androller .137 are preferably detachable. The main driving arm 136 directly engages the adjacent end of the plunger rod and imparts to the plunger rod its'compression movement, the plunger rod'being constrained to partake of this movement by means of its pivotal connection with a crank arm 140 which is pivotally mounted upon the bed plate. The second drive. arm 138 effects the return movement of the plunger rod'by means of its engagement with the arm 1412 of a bell crank'lever 143-,the other arm 14A of which is connected by means of a: rod 145 with the crank'1410. It is obvious that the second drive arm may be provided with a casin ..ancl' roller, identical with the casing 13? and roller 137? so that it will also en.- gage the plunger-rod whereby the plunger is given a double stroke.

.The mechanism described/in the preceding paragraph constitutes drive mechanism for the plunger. and organized with this drive mechanism is other drive mechanism for the shifting mechanism of the feed hoppers and actuating means or drive mechanism" for the operating mechanism of the. tramper'as will be presently described.

The shifting mechanism for'the hoppers and the actuating means or drive mecha nism forthe'tramper includes a pair of posts or vertical shafts150 and 151. up.

standingfrom the bed plate 125 and which The power block carries a r tion of the shaft 151 is. utilized to operate the tramper it will'be termed the tramper shaft.

The feed hoppers are shifted twice for each compression stroke of the plunger .and in order to effect this shifting action .the shaft 150 has fixed thereon at its lower end a sleeve 153 having an arm 154 extendinglaterally therefrom and connected by a connecting rod 155 with a crank arm 156 of an oscillating, shaft 157 journale'd in bearings 158 and connected with one of the cranks 65 for im-. parting the character of motion thereto necessary .to effect shifting of the feed hoppers. On the upper end of the shaft 150 a second sleeve 159 is fixed andcarries a shifting toe 160 which extends laterally therefrom and which is engaged by the wiping cam or arm 161 on thepower block'to effeet the shifting of the feed hopper 40 from loading to baling position and the feed hopper 41 from baling to loading position. a A sleeve 162 is rotatably mounted on the upper 'end of the shaft 151 and carries a shifting toe 163 extending laterally from the sleeve 162' and adapted to be engaged by a wiping cam'or arm 164. The shifting toe 163 operates in a lower plane than the. shifting toe 2 160 and consequently the wipingcam 164 is lower than the wiping cam 61, these wiping cams being also diametrically opposite. The motion which isimparted to the sleeve 162 when the wiping cam 164engages the shifting toe 163 is transmitted-reversed to the shaft 150 and from the shaft 150 it is imparted to the crank 65 to shift the feed hopper 41 to baling position and the feed hop-per 40 to loading position by the motion transmission mechanism constituted by the arm 154, connecting rod 155, crank arm 156 and shaft 157. The means for transmitting the motion of the sleeve 162 to the shaft 150 and for reversing this motion includes an arm 165 extending from the sleeve 162-. Y

and an arm 166 extending from the-sleeve 159 in a direction opposite with respect to the arm 165, the arms 165 and 166 being connected by a cross rod or obliquely extending connecting rod 167. V 1

After each loaded feed hopperi'has been shifted from loading to baling position, the tramper descends to feed the material from the feed hopper into the baling chamber and then is returned-to elevated position that is the tramper partakes once of the cycle of operation after each shifting of the feed hoppers. The drive mechanism for the tramper includes a fixed sleeve 168 keyed or otherwise secured to the shaft 151 and having a toe 169 carried thereby and extending laterally therefrom so as to beengaged by the driving arms-136 and 138. A loose sleeve170 is arranged on the shaft 151 above the fixed sleeve 168 and carries a toe 171 engageable with diametrically opposite wipdisk 176 fixed on the shaft 151 by a link 177 and the arm 175 being connected with an arm 198 on thefixed sleeve 168 by means of a link 179. Motion transmission means is provided for transmitting the motion'of the shaft 151 to the shaft 98 of the tramper operating mechanism and includes a drive arm 1S0 fixed to the shaft151 and pivotally connected with a connecting rod 181 which extends to a crank arm182 formed on one endof a shaft 183 journaled in bearings 184 and having a crank arm 185 connected with a link 186 which also is connected with a crank arm 187- provided onthe shaft 98. When one. ofthedriving arms engage the toe 169 the tr'amperis caused to descend and when oneof the wiping cams 172engages the toe 171 the tramper; is caused to ascend or return to elevated position.

.As the wiping cams or arms 161 and 164 coact with the wiping toes 160 and 162 to impartv motion to the shifting shaft 150 these wiping cams or arms as" wellas these wiping toes will be hereinafter designated as shifting cams and'shifting toes respec{ tively. Similarly the wiping cams 172 and the wiping toes 169 and 171 will be termed tramper cams and toes, respectively, since these cams and. toes coact to impart movement to the tramper shaft 165.

In operation the power rotated in a counterclockwise direction as block 130 I is viewedin Figure 7 either by horse power when the sweeps are attached or by the'gearing 135 when the motor is used;

Assuming'that a charge of material has been fed into" the baling chamber, the next event in the cycle of the operation will be the compression movement of the plunger whichis brought about by the engagement of the driving arm. 136 with the end of the plunger rod. WVhen the plunger has completed its compression stroke the second driving arm 138 engages the bell crank 142 to effect return movement of the plunger and the wiping cam 164 to shift the hopper 41 from baling position to loading position and'to shift the-hopper 40 from loading position to baling position. This shifting of the feed hoppers is brought about since the movement of the shifting toe 160 turns the shaft 150 in one direction and since this movement of the shaft is transmitted to thecrank 65 through the motion transmission-mechanism above described; the flexdrivingarm 136 engages the toe 169- to turn the shaft 151 and through the drive arm 180- and the other elements of the motion transmission mechanism provided between the shaft 151 and the shaft 98 to turn the shaft 98 so as to swing the crank 99 thereof down wardly to cause the downward movement of the walking beam 90 and consequent descent of the tramper. The descent of the tramper feeds the material from the feed hopper into the baling chamber. Immediately after the tramper descends it is lifted or returned by the engagement of one of the arms 172 with the toe 171 which reversely moves the shaft 50 to reversely move the shaft 98 to swing the crank 99 thereofupwardly causing the walking beam to be elevated and the tramper to be correspondingly elevated. By this time the feed hopper 41 has been loaded and the next event in the cycle operations is the second shifting of the feed hoppers so as to bring the feed hopper 11, now loaded, into baling position. This second shifting of the feed hoppers is brought about by theengagement of the wiping cam 16 1 with the shifting toe 163,

this action rotates the sleeve 162 on the shaft 151 and through the arm 165, link' 167 and arm 166 turns the shaft 150 in a direction opposite to that'in which itis turned in the first shifting operation so that the feed hoppers a're :reversely shifted that is to say that the feed hopper 41 is shifted from loaded to baling position and the feed hopper is shifted from baling to loading position. This second shifting of the feed hoppers is followed by a second operation of the tramper which is effected in precisely the same manner as the first operation thereof and following this second operation of the tramper, the'main driving arm 136 again engages the end of the plunger rod to actuate it through its compression stroke. This cycle I of the operation iscontinuous and may be carried on indefinitely. It is only necessary that operators be stationed to successively load the feed hoppers.

If it desired to use a double stroke to'form V, the bail this may be accomplished by simply attaching the casing and roller to the driving arm 138 as has been herein above fullydescribed. If this is done both the driving arms 136 and 138 engage the plunger rod to effect two compression strokes thereof dur- 7 ing each cycle of operation. When the motor post.

and gearing 135 is utilized to drive the power block the post 131 is suitably braced by means of a brace bar B which is connected to the spindle of the gearing 35 and to the ing in said baling chamber, a plurality of feed hoppers movable into baling position over said baling chamber and into loading position away from said baling chamber,
